The antenna meets the requirements of Military Specification MIL-A-5999 for electrical and environmental performance. The antenna is finished with a white Skydrol resistant polyurethane paint in accordance with Military Specification MIL-PRF-85285. The antenna has an operating temperature of -40\u0026amp;deg;F to 160\u0026amp;deg;F and experiences a drag force of 0.22 lb at airspeeds of 400 mph. Precipitation static is minimized through the use of a foam-filled fiberglass construction. The foam also reduces the effects of vibration, shock, and temperature extremes.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eSupplied by Aeronautical Aviation.\u003c\/em\u003e\u003c\/p\u003e","brand":"RAMI","offers":[{"title":"Default Title","offer_id":44134281281614,"sku":"AT-640A\/ARN","price":43966.8,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/7169\/5182\/files\/rami-antennas-at-640a-arn-vhf-marker-beacon-antenna-at-640a-arn-at-640a-arn-vhf-marker-beacon-antenna-1253519141.avif?v=1786120031","url":"https:\/\/aeronautical.co.za\/products\/at-640a-arn-vhf-marker-beacon-antenna-75-mhz","provider":"Aeronautical Aviation (Pty) Ltd","version":"1.0","type":"link"}
